"The knee is great," said Delmas, who had 2014 his season cut short with a torn ACL in December. "My doctors and my training staff have been doing a great job of managing me and making sure I'm doing everything protocol-wise to be able to play the first game of the season.

"I definitely know that I will be ready for the first game of the season."

The Dolphinshavere-signed running back LaMichael James and starting safety Louis Delmas on Friday, according to the Miami Herald and NFL Media, respectively. Delmas' deal is reportedly worth $3.5 million for one year, per Adam Schefter of ESPN.

James, 25, signed with the Dolphins after San Francisco parted ways with him after the opening week of last season. He totaled five carries for nine yards in three games.

Delmas, 27, signed with the Dolphins last offseason and started in 12 of his 13 appearances. He registered 49 total tackles, one sack, one interceptions (for a TD) and three passes defensed.

The Dolphins are awaiting the results of an MRI but believe that safety Louis Delmas suffered a torn ACL in the team's Week 14 loss to the Ravens, the Miami Herald reports.

Delmas was carted off the field Sunday after suffering a knee injury and did not return. If the belief of a torn ACL proves true, Delmas will miss the remainder of the season and quite possibility the beginning of next season.
